IntroductionThe SL1188 is a state-of-the-art universal transit-time flowmeter designed using SLSI technology and low voltage broadband pulse transmission. While principally designed for clean liquid applications, the instrument is tolerant of liquids with small amounts of air bubbles or suspended solids found in most industrial environments. Features of SL1188With distinctive features such as high precision, high reliability, high capability and low cost, the flowmeter features other advantages: Low consumption power, high reliability, anti-jamming and outstanding applicability. Clear, user-friendly menu selections make flowmeter simple and convenient to use. U. S., British and Metric measurement units are available. Meanwhile, almost all-universal measurement units worldwide may be selected to meet customer's requirements. Daily, monthly and yearly totalized flow: Totalized flow for the last 64 days and months as well as for the last 5 years are may be viewed. Power on/off function: Allows the viewing of time and flow rate as power is switched on and off 64 times. Also, the flowmeter has manual or automatic amendment during offline sessions. Self-contained signal output, including relay, open collector, frequency and 4~20mA current loop analog outputs, etc. Parallel operation of positive, negative and net flow totalizes with scale factor (span) and 7 digit display, while the output of totalize pulse and frequency output are transmitted via relay and open collector. Internally configured batch controller makes batch control convenient.
